FUEL-GASIFIER FOR VINllEtilTAIrCOIMIBUS'JFIOI\T ENGINES.

Specification of Letters Patent.

Patented Dee. 9, 1913.

Application led December 11, 1912. Serial No.l 736,181.

To all whom it may concern:

Be it known that l, HERMAN FUCHS, a citizen of the United States, residing at St. Louis in the State of Missouri. have invented new and useful niprovements in Fuel-Gasitiers for lnternal-Coinbustion Engines, of which the following is a specification. y

The" present invention has relation to means for converting fue] of a nature heavier than gasolene into a gaseous inixture for 4use in internal combustion engines of either the four cycle or two cycle type, said lmeans consisting of a gasitier arranged so as to be highly heated by the combustion of the gaseous mixture and to Convert the incomingcharge into gaseous form to be subsequently exploded to drive the piston on its next working stroke.

rlhe invention contemplates a gasiier of novel forni, the same consisting of a cha1nbei' or generating members or a combination of both, said gasiiier being located in the end of the cylinder in which combustion takes place so as to'be heated to a high teinperature and also arranged with reference to the inlet so as to lie in the path of the incoming charge to convert the same into gaseous form.

The invention consists of the novel features, details of construction and combination of parts, which hereinafter will be more particularly set forth, illustrated in the accompanying drawings, and pointed out in the appended claim.

Referring to the drawings; forming a part of the specification` Figure 1 is a sec tional View of an engine of the four cycle type provided with a gasitier embodying the invention. F ig. 9 is a top plan view of one of the generating members. the same consisting of a disk forations. Fig. 3 is a view similar to Fig. 2 of a different form of generating member consisting of a hub and radiating fingers forming a spider. Fig. 4t is a detail perspective view of the generating chamber. Fig. 5 is a sectional view, showing the application of the invention to a two cycle engine.

Fig. 6 is a detail perspective view of a noodi-L fied form of generating chainberhaving annular fins or vribs.

Corresponding and like parts are referred to in the following` description, and indicated in all the views of the drawings, by the saine reference characters.

5 glne, whether of l variety7 the partI ity of openings.

having a plurality of per-- The numerals l and 2 designate well known parts of an internal combustion enthe four cycle or two cycle l being a cylinder and the part 2 the piston arranged to operate therein. A band or ring 3 is bolted or otherwise secured to the end ot' the cylinder l and incloses a space -l which constitutes a combustion chamber. A. plate is secured to the outer end of the band or' ringr 3 and has a central opening in which may be arranged a valve 7, as indicated in Fig. l, or a chamber (i, as designated in Fig. 5. rlhe valve 7 is employed when the invention is adapted for four cycle engines'and controls the fuel in? The fuel may consist of kerosene or let. hydrocarbon. of a greater than gasolene and which ing in Contact with the. elements. As indicated in Fig. l a generating chamber 8 is attached to the inner side of the piate `5 opposite the valve controlled inlet openin, said chamber'being of cup form and having its sides formed with a plural- The chamber 8 is flanged at its upper edge, said iiange beingl pierced and receiving the fastenings byineans of which the generating chamber is attached to the plate 5. Gasit'ying members 9 and l0 have connection with the valve 7 and are movable therewith and are arranged so as to be highly heated by the gaseous mixture when combustion takes` place. The `generating member S) consists of av perforated plate, whereas the member l() is of the forni of a spider comprisingA a hub and radiating` iingers. lt is to be umlerstood that the meinbcrs may be wholly of one kind and any number may bc connected with the valve 7. The stein of the valve may be prolonged and receive the generating members or the latter may be connected to the valve in any manner.

. It is to be understood that thc valve 7 may be unscatcd hv the suction of the piston or by mechanical meansl such as coinnionly provided in the co11s"ruction of in ternal combustion engines. 1When the valve 7 is unsea ted a predetermined quantity of liquid fuel and a given amount of air pass through the opening closed by the Yvalve 7 and the liquid fuel coming` in contact with the heated generating members and chaniber is gasilicd and coniniine'ling' with the atmosphere entering therewith produces the gaseous mixture which may be ignited in specific, gravity is gasilied on coniheated gasifying any manner according to the style of the engine so as to generate motivepower. The generating members and more particularly the generating chamber serve also to insure a thorough mixing of the fuel and air which is essential to produce a combustible mixture.

In the modification 4 through a passage l1 formed in a side of the band or ring 3. T he fuel upon entering the combustion chamber impinges against the generatingchamber 6 and is gasified, said generating chamber being provided with a plurality of projections either in the nature of points, or fins, or ribs, whereby an extendedheated surface is presented so as to instantly convert the fuel into gaseous form. The generating chamber is also formed in its sides with a plurality of openings whereby air and fuel may pass from the inside into the combustion chamber. Fuel may be admitted into the generating chamber 6 by means of a pipe 12 and air may be supplied through a pipe 18.

From the foregoing description, taken in connectionA with the accompanying drawings, the advantages of the construction and of the method of operation will be readily apparent to those skilled in the art to which shown in Fig. 5 the.l lfuel is forced into the combustion chamber the invention appertains, and while I have described the principle of operation of the invention, together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative, and that such changes may be made when desired as are Within the scope kofthe claim ap-4 pended hereto. i

Having thus described the invention what is claimed as new, is Y In an interna-l combustion engine, the combination of a cylinder provided with a fuel inlet, a chamber arranged within the cylinder and extending over the fuel inlet and provided in its sides with a plurality of openings, an inwardly opening valve for closing the fuel inlet and the perforated plate connected with the valve and arranged within the chamber and a spider comprising a hub and radiating fingers connected with said valve and likewise arranged within the chamber.

In testimony whereof I aix my signature in presence of two Witnesses.
